[feature] Identify configuration in remote requests when querying for a packageID

[jgsogo]

When Conan checks if a package for a given configuration is available in a remote, it sends just the package ID. It would be very useful to send the information used to compute that hash:

• We can send all the configuration: package ID computation is reproducible (needed? desired?)
• We can send only the information taken into account to compute the package ID (~conaninfo.txt)

I've been having a look at it and it can be very challenging to pass the information about the configuration to the place where the calls to the remote are being done. I would say we need first to store the actual configuration for a package (settings, options, requirements,...) in the node object to have it available here

conan/conans/client/graph/graph_binaries.py

Line 100 in 7f03c1d

remote_info, pref = self._remote_manager.get_package_info(pref, remote)

Then we can deal with whatever is needed on the RemoteManager side.

That would be accessible in node.conanfile.info object at that point.
